VERY basic help needed (SOHO 91)

[phoneguy2286]

I have a SOHO 91 that I wish to use for very very basic home use. I am not familiar with IOS at all, and this is my first attempt. I have successfully hosed the GUI interface, and have to do everything command line. I have been able to initiate DHCP, but still having a few problems.

I can't get the DNS to work properly, and it looks like every time I reload the router, the interfaces drop and don't come up. Does anyone have a very basic config, or can you look through my config and give me some pointers?

THANKS! If anyone needs PBX assistance, I can possibly return the favor.

[Alterac]

run these:

no ip dhcp pool hh
no ip dhcp pool home1

and add this:

route 0.0.0.0 0.0.0.0 e1


then try to use a computer behind the router.

Wish I could edit posts.

its

ip route 0.0.0.0 0.0.0.0 e1


----------------------------------
Bill

 

[phoneguy2286]

done..no dice..

also tried:

ipconfig/release
ipconfig/renew..

still showing no DNS.

also can't ping out (by name)

and no web page opens

 

[Alterac]

What does the ipconfig /all show on your workstation?

Does it list a DNS server at all?

Can you ping anything from the Cisco itself?


----------------------------------
Bill

 

[phoneguy2286]

it does not show a DNS server...

I seem to remember that I can ping from the Cisco.

I will test tonight again.

 

[burtsbees]

Can you get to the web page of the modem?

Burt

 

[phoneguy2286]

the web page...yes.

remember, somehow I hosed the GUI interface so it doesn't load, but I can get to 10.10.10.1

(I have configured this router with the GUI previously)

 

[phoneguy2286]

cannot ping the public using names from either PC or router

no dns server mentioned in ipconfig, but works with the dlink...(also with no dns server in the ipconfig

First run these two commands.

The default route is backwards. You have
ip route 0.0.0.0 0.0.0.0 Ethernet0

it should be

ip route 0.0.0.0 0.0.0.0 Ethernet1

and for ipconfig, you must run it with teh /all argument in order to see the gateway and the dns servers.

ipconfig /all

you should see something like this:

and for more fun these 3 can be turned off
ip http server
ip http secure-server
ip dns server

like so
no ip http server
no ip http secure-server
no ip dns server

Bill

 

[phoneguy2286]

ok.. I caught the route AFTER I posted...yeah, I wish you could edit AFTER posting

I notice no default gateway....

the modem assigns 192.168.2.XX its address is 192.168.2.1 (pingable from the router, but not the PC)

[Alterac]

the

ip default-gateway 10.10.10.1

Is not required on the router, what we need to specify is the default gateway in the dhcp scope.

do this:

no ip default-gateway 10.10.10.1
ip dhcp pool home
default-router 10.10.10.1


then save the config, and reboot the cisco.

[burtsbees]

I said the web page of the modem, not the router. Under his...
ip dhcp pool home
import all
network 10.10.10.0 255.255.255.0
lease 7

you also need this...
dns-server 192.168.2.1
and under global config...
ip name-server 192.168.2.1

I would have the router NAT and set the modem in bridge mode myself...

Burt

 

[Alterac]

The import all will take care of the dns server under the dhcp scope.

He is also using the Modem to do DNS at the moment, so setting up the ip name-server is redundant.. But the two lines you posts at the very top of this thread should have also fixed it.

----------------------------------
Bill

 

[burtsbees]

I'm still trying to figure out what his modem is doing. That's why I suggested the ip name-server.
Post a sh ip dhcp import...

Burt

 

[phoneguy2286]

Router#sh ip dhcp import

Address Pool Name: home
Domain Name Server(s): 192.168.2.1


yet, I still can't ping "

http://www.yahoo.com"

from the router...

also can't ping 192.168.2.1 from the PC

frustrating...


if I just plug the PC into the modem...it works..

I can get to the modem..I posted some of the settings that I saw..

Interesting...you're not using a crossover cable, are you?
Don't ping Yahoo--try Google. I know that's not the issue, but I though Yahoo blocked icmp echo-replies...
Try setting the E1 interface statically to 192.168.2.55 and change
ip route 0.0.0.0 0.0.0.0 e1
to
ip route 0.0.0.0 0.0.0.0 192.168.2.1
and post sh ip route

Give this a shot and see if it works.

log into the modem and do the following:
1. Right down the DNS server that you modem is getting from you ISP
2. Add a static route in you modem for the following ( 10.10.10.0 255.255.255.0 192.168.2.4)

Note* if you can not add a static route on your modem, it will not know how to get back to your LAN subnet

On your router
--------------
ip dhcp excluded-address 10.10.10.1
!
ip dhcp pool home
network 10.10.10.0 255.255.255.0
default-router 10.10.10.1
dns-server X.X.X.X (add the IP from step 1 above)
!
!
interface Ethernet0
ip address 10.10.10.1 255.255.255.0
!
interface Ethernet1
ip address 192.168.2.4 255.255.255.0
duplex auto

ip route 0.0.0.0 0.0.0.0 192.168.2.1
-----------

now if this works for you than you can move forward and try to dynamically get the DNS from the modem (because the ISP may change their DNS)


ip dhcp excluded-address 10.10.10.1
!
ip dhcp pool home
network 10.10.10.0 255.255.255.0
default-router 10.10.10.1
dns-server 192.168.2.1
import all

Hope this works for ya.

 

[burtsbees]

What the hell? Try changing e1 back to dhcp and then post sh int e1 and sh ip route...if you show an ip address on e1 from dhcp from the modem, but do NOT show a route to that subnet, I'll be stumped and tell you to just get a WIC-1ADSL and be done with it!

[phoneguy2286]

I can ping, and seem to have good access to the internet from the router....ping web addresses, etc..

I cannot reach anything past the router from the PC (internet/modem)

I tried all the above recomendations...nothing really changed..

it's like interface 0 cannot talk to interface 1...

what about re-building the dhcp pool, in order to "refresh" everything there?.. I guess it would be just as easy to RE-default the router and start over...

I am getting the concepts here, thanks for everyone's patience.
